Congenital Central Hypoventilation Syndrome (CCHS)
Use
Congenital central hypoventilation syndrome (CCHS) is a genetic disorder often diagnosed in newborns, characterized by normal breathing while awake but reduced breathing during sleep, leading to various health issues. Genetic confirmation is vital for managing the condition effectively. The PHOX2B gene is primarily associated with CCHS, and identifying mutations in this gene can guide patient care strategies and identify individuals at risk.

Limitations
The test is designed to detect most pathogenic and likely pathogenic variants in the PHOX2B gene, but technical limitations such as sample mix-ups or incomplete knowledge of genes pose a risk for inaccurate results. Not all genetic variants associated with CCHS may be detected due to limitations in the current technology or knowledge. Variants of uncertain significance may be identified, changing as new data emerges.
